Judging from these matches' stats that must be hell of a fast clay. Gil with nine aces, Zivkovic hit many aces on 2nd serve, few breaks (or no breaks)
Quito is on ~3000 m elevation. Air is way thinner than usual, balls fly. Decent server with a good fitness can go very deep here. Judging by that Rufin should be the first favorite to take the title.
